WATER-GAGE.

Specification of Letters Patent.

Patented May 19, 1908.

Application filed October 12,, 1907. Serial No. 397 ,082.

To all whom it mag concern:

Be it known that 1, CHARLES AL'KENNEY, a citizen of the United States,residing at Trenton, county of Mercer, State of New J ersey, haveinvented a new and useful Water- Gages, of which thefollowing is aspecification.'-

This invention relates to water and other liquid gages ada ted forgeneral use and especially adapted or use upon locomotive and otherboilers, and the invention has for its object to provide a gage thatshall be simple and inexpensive to produce, of few parts] strong anddurable, easy to take apart to renew'packings or the gage glass shoulditbecorne broken, and so constructed that the circulation of the wateror other I glass may be seen from any direction. With these and otherobjects in view I have devised the simple and novel gage, of which thefollowing description in connection with the accompanying drawing is aspecification,

reference characters being used to indicate the several arts.

Figure 1 1s an elevation of my novel gage complete; Fig. 2 alongitudinal section; and Fig. 3 is a transverse section on the line 3-3in Fig. 2.

10 denotes the case or frame of my -novel gage, which is provided ateach end with an internal screw thread as at 11 and with a plurality oflongitudinal openings 23 through which the gage glass 12 is visible. Thegage glass is provided at each end with a boss 13 and each boss isprovided with a longitudinal opening 14 communicating with the cham ber15 within the gage glass to )rovide free liquid. The boss at each end ofthe gage glass engages a socket 16 in a nipple 17 which is externallythreaded to engage the thread 11 in the case. 18 denotes packingwashers, preferably of rubber, which rest u on shoulders 19 at the endsof the gage g ass and surround the bosses.

20 denotes copper or other metallic washers which may be interposedbetween the ends of the nipples and the packing washers.

21 denotes nuts, preferably spanner nuts,

apart'will be readily understood from the drawing. In assembling, thepacking washers, and the metallic washers if used, are placed over thebosses, the gage glass is placed within the body and the nipples areturned into engagement with the threads 11 at the ends of the case, thebosses at the ends of the gage glass being received in the sockets inthe nipples. The parts are then looked in place by tlghtening up nuts 21which engage the threads upon the nipples and bear against the endsofthe case. bhoul'd the gageleak, the leak can usually be stopped byturning back one or both of the nuts 21 and turning the nipples inwardslightly to compress the packing washers, the nuts being then tightenedup again. Owing to the fact that the nipples 17 extend over and receivethe bosses of the glass, the packing washers being located between theinner ends of the nipples and the shoulders which surround the bases ofthe bosses, no aniount of tightening up can cause the washers tointerfere with the assage of fluid through the openings in the osses andnipples. Should new packing washers be required .or the glass becomebroken, it is simply necessary to turn back the upper nutslightly andthen turn the-nipple out of engagement with thecase. This willpermit-the glass and packing washers to be removed and a new glass ornew packing washers to be placed in the gage in a moments time. Mypresent construction onables me to reduce the original cost of the gageboth in-material and labor to the minihaving a boss at-each end andshoulders surrounding said bosses, a case having openings through whichthe glass may be seen, said case beinginternally screw threaded at itsends, nipples engaging the threads in the case and having sockets intowhich the bosses cit-- tend and packin washers between the inner ends ofthe nipples and'thc shoulders of the glass.
